A new air-assisted liquid-liquid microextraction method based on alkanol nanostructured supramolecular solvents coupled to spectrometric analysis was developed for extraction, preconcentration, and spectrophotometric determination of morin. Al(III)-morin complex was performed at pH 4.5. Four different alkanol-based SUPRAS (supramolecular solvents) were prepared for the separation and preconcentration of Al-morin complex from aqueous solution by using vortex and centrifugation. Effect of analytical variables and tolerance limit of matrix ions were investigated. Under the optimum conditions, detection limit, quantification limit, relative standard deviation, preconcentration factor, and enhancement factor were found as 3.5 µg L, 10 µg L, 3.1%, 120, and 95, respectively. The accuracy of the method was performed with standard addition. The obtained results demonstrated the applicability of the method for the separation, preconcentration, and determination of morin in fruit and beverage samples. The method also complies with green chemistry principles as it uses green solvents, reduces reagent volumes, and produces low amounts of waste.

开发了一种基于链烷醇纳米结构超分子溶剂并结合光谱分析的新型空气辅助液-液微萃取方法，用于桑色素的萃取、预富集和分光光度测定。在pH 4.5条件下形成铝（III）-桑色素络合物。制备了四种不同的基于链烷醇的超分子溶剂（SUPRAS），通过涡旋和离心从水溶液中分离和预富集铝-桑色素络合物。研究了分析变量的影响和基质离子的耐受限度。在最佳条件下，检测限、定量限、相对标准偏差、预富集因子和增强因子分别为3.5 μg/L、10 μg/L、3.1%、120和95。该方法的准确性通过标准加入法进行验证。所得结果证明了该方法在水果和饮料样品中分离、预富集和测定桑色素的适用性。该方法还符合绿色化学原则，因为它使用绿色溶剂、减少试剂用量并产生少量废物。
